Karen Petrou: Why Banks Should Want New Capital Rules
Ever since the election, a lot of bankers have loudly hummed “Ding-dong, regs are dead, the wicked capital regs are dead.” There is no question that the wicked witch’s demise was warranted, but I’m not so sure about the merits of a similarly-ignominious and total end for the capital rules. As FedFin reports make clear, too much in these proposals is wrong-headed, even as they may now be revised. Still, it’s important also to remember that leaving the current rules unchanged leaves as is many provisions that are anachronistic or demonstrably conducive to shadow banking. There’s never been a better time than now to think about how best to modernize large-bank capital rules without unnecessarily eviscerating large-bank competitiveness.
